Overview of this book

Author Carlos R. Morrison (Staff Scientist, NASA) will empower the uninitiated reader to quickly assemble and operate a Pi3 supercomputer in the shortest possible time. The lifeblood of a supercomputer, the MPI code, is introduced early, and sample MPI code provides additional practice opportunities for you to test the effectiveness of your creation. You will learn how to configure various nodes and switches so that they can effectively communicate with each other. By the end of this book, you will have successfully built a supercomputer and the various applications related to it.

Creating a Mountable Drive on the Master Node

Summary


In this chapter, we learned how to create a common user for all nodes. We achieved this by initially creating a new user for the master node, and then creating a password for that new user. We then employed a similar procedure for the slave1 node. Next, we generated a special key on the master node, copied the special key to the slave1 node, and then edited the .bashrc file on the master node to facilitate seamless special key access to all nodes in the super cluster. Finally, we used the which command to uncover the path to keychain. Chapter 6, Creating a Mountable Drive on the Master Node, discuss how to create a mountable drive on the master node. Go ahead and exit to the pi user pi@Mst0:~ $. If you are not now at the master node, close out the terminal window, ssh back into the master node.
